The comedian made a quick video to challenge Kevin to a $5 million match — any match. Williams' Conspiracy Theory tour is heading to Philadelphia on Saturday and Katt wants Kevin to put up or shut up.

“I got a show at your hometown–in Philly. I’ma tape my special there on that stage,” Katt informs in the minute-long video. “We could put whatever you want. A full-court basketball court. A boxing ring. Two microphones for a rap cypher. Or you can get your ass dusted in comedy on that stage. But it’s $1 million up for each one. That’s $5 million, Mr. $28 Million in Forbes. I’ll be bringing mine in cash, mitch. Bring yours however you want.”

If these two were to engage in a comedy standoff, who do you think would provide a better 30 minute set: Katt Williams or Kevin Hart?
